 'Production and Characterisation of Amorphic Diamond Films produced by pulsed laser ablation of graphite'

 Diamond Rel. Mater.(1997), 6, 569-73

 Amorphic diamond (a-D) films have been grown by pulsed laser deposition using an ArF excimer laser to ablate material from a dense, ultrapure graphite rod. Deposition rates have been investigated as a function of incident pulse energy and of time. The resulting films have been analysed by scanning electron microscopy and by laser Raman spectroscopy, and their electron emission characteristics tested. We confirm the potential of a-D films for use a cold cathode material.
